Intentional states

Don t make your thesis merely an announcement of your subject matter or a description of your intentions. State an attitude toward the subject. 

Our intention is to give a brief survey of advanced theoretical methods used to detennine the electronic and geometric stmcture of solids and surfaces. The electronic stmcture encompasses the energies and wavefunctions (and other properties derived from them) of the electronic states in solids, while the geometric stmcture refers to the equilibrium atomic positions. Quantities that can be derived from the electronic stmcture calculations include the electronic (electron energies, charge densities), vibrational (phonon spectra), stmctiiral (lattice constants, equilibrium stmctiires), mechanical (bulk moduli, elastic constants) and optical (absorption, transmission) properties of crystals. We will also report on teclmiques used to study solid surfaces, with particular examples drawn from chemisorption on transition metal surfaces. 

As of this writing (ca 1994) none of the newer lead smelting technologies has been adopted in the United States. Also, no new lead mine has opened in the United States since the early 1980s. Most of the known U.S. reserves for lead are located in federally owned land in Missouri future mine development depends on the outcome of the U.S. government s intent to reform the Mining Law of 1872. 

Companies in the United States, Japan, and Europe are actively working to commercialize CdTe PV technology. CdTe PV modules are available in limited quantities and sizes from one Japanese manufacturer, and two U.S. companies (Golden Photon in Colorado and Solar Cells Inc. in Ohio) have announced their intention to market CdTe PV products in the near future. 

Interface states played a key role in the development of transistors. The initial experiments at Bell Laboratories were on metal/insulator/semiconductor (MIS) stmctures in which the intent was to modulate the conductance of a germanium layer by applying a voltage to the metal plate. However, only - 10% of the induced charges were effective in charging the conductance (3). It was proposed (2) that the ineffective induced charges were trapped in surface states. Subsequent experiments on surface states led to the discovery of the point-contact transistor in 1948 (4). 

Economic Factors. Annual usage is under 10 metric tons, and is largely consumed ia the United States. Minor quantities are used in both Europe and Japan. Prices vary by appHcation but exceed 200/kg. Ethyl Corp. has announced its intent to divest or exit this business. At present they are the sole suppHer. 

In 1989 BASE announced its intention to market in the United States a polysulfone, Ultrason S, and a polyethersulfone, Ultrason E. Both materials would likely be made in Germany. World consumption and prices of polysulfones are given in Table 12. 

A written respiratory protection program is required when necessary to protect the health of the employee from workplace contaminants or when the employer requires the use of respirators. A limited written program is also required when respirators (other than dust masks) are being voluntarily worn by employees. This latest document states It is the intent of the standard that the employer would not be required to incur any costs associated with voluntary use of filtering facepieces other... 

Very recently, the scientific interests of several leading theoretical laboratories have turned to studies of quenched-annealed fluids. To the best of our knowledge, there has not been a comprehensive review of the theoretical studies of quenched-annealed fluid systems. Our intention in this chapter is to fill, at least partially, an existing vacuum. Evidently, it is impossible to discuss the state of the art in this rapidly developing area in every detail in a single paper with restricted dimensions. We will omit, for example, the discussion of the fundamentals of the replica method for lattice systems, referring the reader to a monograph [1].
